My invention relates to improvementsin Water tube boilers, and refers particularly to a boiler of this type fory heating purposes.

One obj ect of my invention is the provision `:s of a water tube boiler composed of sections adapted to be placed one upon the other in vertical relation with the sectionsof practically uniform size and shape.'

Another object of my invention is thepro- 1o vision of a sectional water tube yboiler in which the sections are of rectangular lform in general outline to cause them to fit snugly together in vertical formation.

Another object of my inventionvis the pro* vision of a Water tube boiler composed of rectangular sections of uniform vsize Y and which will be so disposed and connected as to insure ak circulation of water both ina vertical and horizontal direction `and thus insure the most practical heating with the proper amount of fuel. f

Another object of my invention is the provision of a watertube boiler which can be easily repaired when found necessary and H which will allow the entire replacement of a part or section at a small Vcost and. in short order.

Another object of my invention is thel production of a water tube boiler which will permit access to its interior for purpose of repair or cleaning and whichcan be quickly assembled, the shape ofthe sections allowing them to be carried through a window opentrnother object of my invention is the provision of a water tube boiler which will possess merit in point 0f simplicity and durability of construction, which can be soldat a comparatively low price .i and which will be thoroughlyeliicient and` practical from every .50 cordance with andembodying my invention.

Figures 13 and 14: represent detail views of the waterV leg or jacket structure.

Figure 15 represents a front elevation of a modified form ofmybOiler, and

Figure 16 represents a central longitudinal sectional view of the said modified form.

y Referring by numerals to the drawings in which the same numbers of reference denote like parts in allthe views ofthe drawings:

` The numeral 1 designates the base of my boiler,which is formed with the ash pit 2, and with a door 3, to` permit access to said pit, andy to each side ofthe base and disposed longitudinally thereof are the angled or ianged rails 4, which support the panelstructure las will presently appear.

On the base is4 supported the section 5, which contains there chamber-6, and upon this section is mounted in a vertical tier-the series of like sections 6, 7andf8, all of said sections being of substantially rectangular form in general outline and the fire pot section being somewhat wider than the surmounting sections, and while only four sections are shown in the drawings, it will be understood that any number of sections may be used in series according to conditions and requirements. Y

From this construction it will be noted that the structure as a whole forms a vertical boiler with similar individual sections of rectangular form which rest one upon the other and each of these sections is provided fore and aft with water legs or jackets 9, 10, 11 and 12, and that in the fire chamber are arranged the series of horizontal water tubes 13, and in the surmounting sections are also arranged the series of similar horizontal water tubes 14, 15 and 16, all of which tubes lead into the said water legs of said individual sections.

The front wall of the 4series of sections noted is provided with openings 17, which register with the tubes of each section, such openings beingnormally closed by caps 18, and which arrangement allows the caps to be removed for the. purpose of flushing said tubes or inserting a suitable cleaning tool to remove scale or foreign matter from the tubes, and this horizontal arrangement possesses great advantage over an inclined arrangement as the cleaning tool can be easily moved back and forth, or a hose easily inserted to clean with a stream of water.

It will thus be noted that the sections are each provided with water legs at the front and rear and also that each section has mounted therein and leading to said water legs a series of similar horizontal water tubes and that the water inlet 19, is providedto supply the water to said tubes, and to connect the said water legs I provide at each end of the sections the elbow connections 20, 21 and 22, arranged as shown in Figures 1 and 2, and by this arrangement the water passes from the lower or fire pot section to the neXt section above and from said neXt section to the above sections from the lower to the upper forming a horizontal flow of water direct from the lower or fire box chamber throughout the series, and to provide an additional vertical flow of the water I provide the lower corners of each section above the fire pot section with a cut out portion 23, which admits the vertical sleeves or nipples 24, to connect the sections at their corners and also to form a vertical water passage, and this is of great importance as in addition to forming a mean-s for connecting the sections in series, these nipples form a means to direct the water in a vertical line.v

The upper section of my boiler is formed with an opening 25, surrounded by a flanged frame 26, and to which a stack connection may be secured and is further provided with passages 27, in the upper wall of its water legs which lead to the hollow fore and aft supports 28, of the twin tanks or drums -29, which tanks are provided with the service outlet 30, and with the smaller outlets 31, which are connected by the pipes 32, with the pressure gage 33, and by pipe 34, with the vertical pipe 35, carrying the relief valve 36 and the water gage 37, as most clearly shown in Figure l.

For the purpose of enclosing the sides of myboiler and to insulate the boiler in an air tight manner I provide a panel construction, which comprises an outer metal sheet 38 and an inner parallel arranged metal sheet 39, with an insulating layer 40, of asbestos or other desirable insulating material, which are fastened in close relation by the corner clamp-s 41, and by the rails 42, and fastenings 43, the whole forming a panel mounting or frame secured at the upper and lower edge to the sides of the boiler, as most clearly shown in Figures 2, 9, 10, 10X, 11 and 12, which makes an ornamental covering and also provides an air tight insulation for theI boiler.

From the foregoing description taken in connection with the drawings the operation and advantages of my sectional water tube boiler will be fully understood and appreciated, and it will be apparent that the boiler is compact and small in size but insures a large heating capacity; also that the structure can be easily built or assembled at any time and in any character of building; also that the water circulates both in a vertical and horizontal direction insuring the most practical heating results; also that the boiler may be used either with coal or oil as a fuel and prove satisfactory with either fuel; also that the parts of the boiler are easily and quickly accessible for purpose of cleaning or repair; also that the enclosing panels may be applied or removed when necessary and that they form a complete airtight insulation.

In the modied form of my boiler shown in Figures 15 and 16, I provide la more siniple structure and which is more compact and smaller in size, and in this form I employ a lower section 44, in which is provided a combustion chamber 45, which may use coal, oil, or gas, as found desirable, and this lower section has the front and rear water chambers 46, to which lead the water inlet 47 at the rear and the water inlet 48, at the front, and the section is also provided with the fire chamber door 49 and the outlet 50, to the stack.

I also provide said lower section with the series of water tubes 51, and on this lower section is placed the section 52, having the front and rear water chambers 52, and service outlets 53, and outlet 54, for connection with a pressure gage, water gage, and safety valve, and this section is also provided with the Water tubes 55, and above said tubes are arranged the water drums 56, and a vertical battle 57, is also provided, as shown in Fig. 16.

I claim:

l. A sectional water tube boiler composed of a lower lire chamber section and a series of sections mounted in vertical relation upon said tire pot section, water legs at the front and rear end of all of said sections, horizontal tubes in said sections in communication with said Water legs, elbows connecting said water legs to provide circulation between said sections, nipples connecting and securing said sections and forming vertical circulating means, a passage in the upper section to connect with a stack, twin drums or tanks in communication with the water legs of the upper section, and a pressure gage, relief valve, and Water gage associated with lsaid tanks.

2. A sectional Water tub-e boiler, composed of a lower fire chamber section and a series of sections mounted in Vertical relation upon said ire chamber section, water legs at the front and rear end of all of said sections, horizontal tubes in said sections in communication with said water legs, elbows connecting said water legs to provide circulation, insets at the corners of said sections, nipples connecting and securing said sections and forming vertical circulating means and ar ranged within said insets, a passage in the upper section to connect with a stack, a tank in communication with the water legs of the upper section, and a pressure gauge, relief valve and water gauge associated with said tank.

In testimony whereof I aifiX my signature.
